[Penis friction edema: not a venereal disease]

Abstract

A 35-year-old man presented with a local swelling of the penis, which increased until the entire penis was thick and swollen. After infectious and obstructive causes had been eliminated, a diagnosis of 'penis friction oedema' was made. The swelling disappeared during several weeks of abstinence from sexual intercourse. Penile abnormalities can be divided into venereal diseases (STDs), incidental affections of the skin or mucous membranes in that location, and disorders of vascularisation and lymph drainage. A traumatic disorder of lymph drainage is sometimes referred to, unjustifiably, as 'penile venereal oedema'; it is a result of friction and manifests itself as local or total penile oedema or as a cordlike congestion of the lymphatic vessels. The diagnosis is by exclusion and the treatment is temporary abstinence from sexual intercourse.
